What is the primary reason for diluting spirits before serving?

The primary reason for diluting spirits before serving is to achieve the desired serving strength. Many spirits are distilled to a high alcohol content, which can be quite intense for some consumers. By diluting spirits with water or mixers, the alcohol strength is lowered, making it more palatable and enjoyable, especially for those who prefer a milder taste. This practice not only enhances the drinking experience but can also help to bring out the flavors and aromas that might otherwise be overwhelmed by the high alcohol concentration.

While there are other reasons spirits may sometimes be diluted—such as to enhance aroma or create a smoother mouthfeel—those are secondary to the primary purpose of making the spirit more suitable for consumption at a desired strength. Sweetness is typically a result of the ingredients used in the spirit or mixers added, rather than a direct result of dilution.
